Grór was a Dwarf and a significant leader among the people of Durin.

Life[edit | edit source]

Birth and early Life[edit | edit source]

He was born into the House of Durin in T.A. 2563 during its last troubled years in the Grey Mountains. He was the youngest of the three sons of King Dáin I, who ruled Durin's folk during their war with the Dragons from the Northern Waste. When Grór was just twenty-six years old, a Cold-drake attacked Dáin's hall, and killed his father and brother, Frór.

The two remaining sons resolved to leave the Grey Mountains with their people and settle elsewhere. As the elder brother, Thrór inherited the Kingship, and led his people back to Erebor in the southeast. Young Grór however traveled east, to the Iron Hills, where he founded a realm of his own becoming the first Lord of the Iron Hills.[1]

Lord of the Iron Hills, and later life[edit | edit source]

Grór saw many mishaps and tragedies during his rule. The kingdom of his brother Thrór was destroyed by the Dragon Smaug, and Grór's son and heir, Náin, was killed at the Battle of Nanduhirion before he could inherit. Grór's rule passed instead to his grandson.

However under Grór's leadership the Iron Hills also became the strongest of the realms in the North both economically and militarily, having the capability of standing between Sauron and his plans to destroy Rivendell and taking back the lands of Angmar. Their numbers were also boosted by many of their fellow Longbeards fleeing from the Sack of Erebor and later those wandering in exile.

Grór ruled the Dwarves of the Iron Hills for two hundred and fifteen years, and was succeeded by his grandson Dáin. He died in T.A. 2805 at 241 years of age.[1]

Many years later, at the Battle of Five Armies, Thrór's last descendant, Thorin, was lost. Dáin II Ironfoot inherited the high Kingship of Durin's folk, a title that remained with the descendants of Grór.

Etymology[edit | edit source]

Jim Allan has suggested that Grór (like Gróin) is derived from Old Norse gróa ("to grow"), thus meaning "Growing-one".[2]
